Quick Steps to Make Easy Tuna Casserole
Preheat the oven to 425ยฐF to ensure a bubbly, golden finish. Cook the egg noodles just until al dente so they donโt turn mushy while baking. Sautรฉ diced onion and celery in butter until tender and fragrant.
In a large mixing bowl, combine the cooked noodles, onion mixture, thawed peas, condensed cream of mushroom soup, milk, shredded cheddar, drained tuna, and fresh parsley. Stir gently until everything is evenly coated.
Transfer the mixture into a 2-quart baking dish, spreading it out evenly. Combine panko, melted butter, extra cheddar cheese, and parsley, then sprinkle this crumb topping generously over the casserole.
Bake for about 18โ20 minutes until the top is golden and the sauce is bubbling at the edges. Let it cool slightly before serving for the best texture.

Tips & Tasty Variations for Easy Tuna Casserole
For added flavor, try mixing in a splash of Worcestershire sauce or a squeeze of fresh lemon juice to brighten the creamy base. A sprinkle of garlic powder or smoked paprika adds a new layer of depth.
Swap frozen peas with sweet corn or chopped cooked broccoli for a twist. For a richer topping, blend in a handful of grated parmesan with the breadcrumbs. If you prefer extra crunch, add crushed potato chips instead of panko.
